To identify the differentially expressed genes between each of the 3 levels of oxygen, you need to define 3 pairwise contrasts.

说明

100 XP

The ExpressionSet object eset with the hypoxia data and the design matrix you just created (design) have been loaded in your workspace.

  • Use makeContrasts to define the 3 pairwise contrasts. Remember to use the column names from the design matrix without using quotation marks.
